The National Stadium ― Bird’s Nest News Release 2008/7/1
中國北京國家體育館“鳥巢”與全球最知名的固體力學/流體力學/電磁學的分析模擬軟體 ANSYS 完美結合
| The Beijing National Stadium, or Birds Nest, is the main stadium for the Beijing games and was designed by Swiss architects Arup Herzog and De Meuron to incorporate universal qualities of beauty and to be sensitive to Chinese cultural traditions. This venue will host the opening and closing ceremonies as well as the track and field events. The 332 meter by 296 meter by 68-43 meter tall elliptical structure has an unusual lattice steel structure. One group of researchers simulated the structure using ANSYS software and static and dynamic analysis. Another group used simulation to evaluate the structural effects of a spatially varying Richter 7 earthquake in which there were multiple support excitations and multiple natural frequencies in the one to six Hz range. In this study, displacements of up to 0.9 meters were predicted. |

The Aquatic Center ― Water Cube
Word Count: 67 (Possibly don’t include this example)
Also designed by Arup, PTW and the China State Construction and Engineering Corporation, the Aquatics Center is a concrete and steel construction with a frame that looks like soap bubbles. It is covered by a prototype clear Teflon plastic cladding film (ETFE). The skin is double-layered to allow for natural ventilation. Air circulation and fire and smoke safety analyses were conducted on the design using ANSYS software. |

Table Tennis Gymnasium
Word Count: 120
As one of the most popular sports in China, table tennis warranted a worthy venue. The gymnasium’s roof, incorporating a central transparent ball shape, is designed in keeping with both traditional features and the modern Beijing style. Researchers at Tongzi University used ANSYS software for a nonlinear analysis of the pre-stressed, steel truss, shell roof structure. This hybrid tension design was assessed for pre-stress, nonlinear buckling and the ultimate bearing capacity of the roof. Beam 188 element was applied and geometric nonlinearity and support condition nonlinearity caused by the slide bearing were all taken into account. Analysis determined that the central rigid ring (5m x 2m) and roof brace system were responsible for the strength and rigidity of the roof. |

Badminton Arena
Word Count: 100
Badminton ― another popular sport in China, like table tennis ― will be played in an arena designed in the shape of a shuttlecock. The building is a single-layer reticulated shell structure that is 62 x 46 meters. Researchers at Beijing University of Technology used ANSYS software to perform a nonlinear stability analysis that took into account shear deformation rotational inertia effects using beam 188 element ― 1 3-D linear finite beam element. Based on ANSYS Parametric Design Language (APDL), a model was constructed and the simulation results indicated that the stability of the structure is the worst if the initial geometry disfigurement ratio is approximately 1/250. |
